RESUMO

Competency in forms of scientific communication, both written and spoken, is essential for success in academic science. This study examined the psychometric properties of three new measures, based on social cognitive career theory, that are relevant to assessment of skill and perseverance in scientific communication. Pre- and postdoctoral trainees in biomedical science (N = 411) completed online questionnaires assessing self-efficacy in scientific communication, career outcome expectations, and interest in performing tasks in scientific writing, oral presentation, and impromptu scientific discourse. Structural equation modeling was used to evaluate factor structures and model relations. Confirmatory factor analysis supported a 22-item, 3-factor measure of self-efficacy, an 11-item, 2-factor measure of outcome expectations, and a 12-item, 3-factor measure of interest in scientific communication activities. Construct validity was further demonstrated by theory-consistent inter-factor relations and relations with typical communications performance behaviors (e.g., writing manuscripts, abstracts, presenting at national meetings).

RESUMO

We studied social-psychological effects over time of a faculty-mentor workshop intervention that addressed attitudes associated with language variety and their impact on scientific communication (SC) skill development of PhD and postdoctoral STEM research trainees (N = 274). Six months after their mentors attended the workshop, all mentees had significant gains in productivity in speaking tasks. In particular, mentees with high language discomfort rated their quality of communication with their mentor and their enthusiasm about communicating more highly (p < .05 for both measures), compared to mentees with low language discomfort. In addition, mentees raised speaking nonstandardized varieties of English reported significant reductions in discomfort related to language use (p = .003), compared to mentees raised speaking standardized English. We conclude that training mentors to understand and respond to language diversity and development results in multiple beneficial outcomes for mentees, including the amelioration of language-variety related discomfort in the research environment.

RESUMO

International graduate trainees, many of whom are non-native English-speaking (L2) trainees, comprise more than half of graduate-level trainees in STEM, but little is known regarding factors that influence their career intentions, especially those that foster their growth as scientists to achieve their full potential in research. Thus, the purpose of our studies was to examine the relationship between L2 status and contextual factors that help shape the learning experiences and plans for research-focused careers. Study 1 collected cross-sectional survey data from doctoral and postdoctoral trainees (N=510) from research institutes in the Texas Medical Center in Houston. We examined which factors were associated with research career intentions using multiple linear regression analysis. Study 2 collected longitudinal data from doctoral and postdoctoral trainees (N=185) from 71 institutions in 33 states in the U.S. Repeated measures of career intentions were evaluated using mixed-effect modeling, and cross-tabulation analysis evaluated job-seeking behaviors by language status. Results showed that L2 trainees had stronger intentions to pursue research careers than did native English-speaking trainees (L1), controlling for other variables. Mentoring, trainee self-efficacy, and the perception of working more than mentors expected influenced each career intention differently. In Study 2, career intentions did not change over time for L2 or L1 trainees, but L2s preferred working in higher education or research institutes more than L1s. L2s, however, were more likely to be in early stages of seeking jobs compared to L1s. These findings provide implications for research mentors, advisors, and academic administrators in facilitating L2 career advancement and success.

RESUMO

A key part of keeping doctoral and postdoctoral trainees in STEM research careers is mentoring. Our previous research indicates that mentoring trainees in scientific communication (SC) skill development increases research career intention through two social-cognitive constructs, self-efficacy in and outcome expectations for acquiring SC skills, as well as science identity. While many mentor training interventions exist, no programs focus on developing SC skills specifically. The "Scientific Communication Advances Research Excellence" (SCOARE) program trains mentors to address trainee scientific communication (SC) skill development as an innovative approach to increase trainee research career persistence. The SCOARE training is a half-day workshop for faculty mentors of research trainees at five sites nationally. Informed by previous research, workshop content focuses on practical, effective mentoring strategies to develop trainee speaking and writing skills. Anonymous evaluation data collected after each workshop indicates participant satisfaction and reported positive increases in skills and knowledge in applying new and various techniques when mentoring trainees (skills) and how linguistic bias influences our perception of others (knowledge). This article outlines the research-based development of the SCOARE program, the first two years' of workshop evaluations showing positive increases in skills and knowledge, and lessons learned to increase participant satisfaction with the program.

RESUMO

BACKGROUND: Studies on parent-child correlations of physical activity have been mixed. Few studies have examined concurrent temporal patterns of physical activity and sedentary behaviors in parents and children using direct measures. The purpose of this study was to examine parent-child activity correlations by gender, day of week, and time of day, using accelerometers - a method for direct assessment of physical activity. METHODS: Accelerometers were used to assess physical activity and sedentary time in 45 fathers, 45 mothers and their children (23 boys, 22 girls, mean age 9.9 years) over the course of 4 days (Thursday - Sunday). Participants were instructed to wear accelerometers for 24 hours per day. Data from accelerometers were aggregated into waking hours on weekdays and weekends (6:00 am to midnight) and weekday after-school hours (3:00 - 7:00 pm). RESULTS: Across the 4 days, the mean minutes per day of moderate-to-vigorous physical activity (MVPA) for fathers was 30.0 (s.d. = 17.3), for mothers was 30.1 (s.d. = 20.1) and for children was 145.47 (s.d. = 51.64). Mothers' and fathers' minutes of MVPA and minutes of sedentary time were positively correlated with child physical activity and sedentary time (all ps < .05, with the exception of mothers' and children's sedentary time on weekdays from 6 am to 12 am). Multivariate linear regression analyses resulted in significant effects between parents and children for MVPA across all time segments. For sedentary activity, significant associations were observed only between father and child on the weekend. Sedentary activity of parents and children were not related for other time segments. Models examining the associations of one or two parents with high levels of MVPA or sedentary time indicated a dose response increase in child activity relative to parent. CONCLUSIONS: Greater parental MVPA was associated with increased child MVPA. In addition, having two parents with higher levels of MVPA was associated with greater levels of activity in children. Sedentary time in children was not as strongly correlated with that of their parents. Findings lend support to the notion that to increase childhood activity levels it may be fruitful to improve physical activity among parents.

RESUMO

The number of biomedical sciences PhDs persisting in academic faculty careers has been declining. As one potential influence on trainees' intention to persist, we investigate the development of scientific communication (SC) skills, hypothesizing that attitudes and behaviors regarding scientific writing, speaking, and presenting predict academic research career intention, through science identity. After adapting a social-cognitive career theoretical model of SC to include science identity and mentor practices, we conducted a longitudinal survey of 185 doctoral and postdoctoral fellows. Structural equation modeling was used to examine relationships among SC productivity, SC self-efficacy, SC outcome expectations, mentor practices in SC, science identity, and research career intention. Results confirmed the overall model and revealed additional specific pathways: SC productivity and SC outcome expectations directly predicted career intention; SC productivity and mentor practices predicted science identity through SC self-efficacy. Demographic factors did not predict intention when controlling for SC variables. Findings support a model of SC skill development as a predictor of research career intention (R2 = .32). The finding that SC language use predicts science identity has important sociolinguistic implications. The key factors in this process are actionable at the trainee, mentor, and institutional levels, suggesting potential for SC interventions to increase career persistence.

RESUMO

OBJECTIVE: This study examined parent-child attitudes on value of specific types and intensities of physical activity, which may explain gender differences in child activity, and evaluated physical activity as a mechanism to reduce time spent in sedentary behaviors. DESIGN: A community sample of 681 parents and 433 children (mean age 9.9 years) reported attitudes on importance of vigorous and moderate intensity team and individually performed sports/activities, as well as household chores. Separate structural models (LISREL 8.7) for girls and boys tested whether parental attitudes were related to child TV and computer via child attitudes, sport team participation, and physical activity, controlling for demographic factors. MAIN OUTCOME MEASURES: Child 7-day physical activity, sport teams, weekly TV, computer. RESULTS: Parent-child attitude congruence was more prevalent among boys, and attitudes varied by ethnicity, parent education, and number of children. Positive parent-child attitudes for vigorous team sports were related to increased team participation and physical activity, as well as reduced TV and computer in boys and girls. Value of moderate intensity household chores, such as cleaning house and doing laundry, was related to decreased team participation and increased TV in boys. Only organized team sports, not general physical activity, was related to reduced TV and computer. CONCLUSION: Results support parents' role in socializing children's achievement task values, affecting child activity by transferring specific attitudes. Value of vigorous intensity sports provided the most benefits to activity and reduction of sedentary behavior, while valuing household chores had unexpected negative effects.

RESUMO

PURPOSE: This research describes the development of a measure of the general attribute of "athletic" in adolescents, encompassing exercise, sport, and physical activity. Based on a theoretical model supported in adults, the 40-item Athletic Identity Questionnaire (AIQ) for adolescents assesses four dimensions: appearance, competence, importance of activity, and encouragement from three sources: parents, friends, and teachers/other adults. METHODS: Structural equation modeling was used to evaluate the hypothesized four-factor model in a development sample of 408 adolescents in eighth grade (mean age 13.4 yr). A separate sample (N = 1586) was used to cross-validate the final model. Construct validity was examined by testing the model's relationship to self-reported (Modifiable Activity Questionnaire-Adolescent, Previous Day Physical Activity Recall, Youth Risk Behavior Survey) and objectively measured physical activity (MTI accelerometer in sample 3, N = 100). RESULTS: Confirmatory factor analysis supported the four-factor structure, and there was also support for a higher-order model. LISREL correlations between the AIQ factors and self-reported physical activity ranged from 0.32 to 0.61, TV watching from -0.20 to -0.50, and sport-team participation from 0.20 to 0.54. Pearson correlations between the AIQ factors and MTI vigorous physical activity ranged from 0.09 to 0.26 and MTI moderate from -0.06 to 0.22. CONCLUSIONS: Findings support the factorial and construct validity of the AIQ for adolescents.

RESUMO

BACKGROUND: In young children, the eating environment is an important social context within which eating behaviors develop. Among many low-income young children, the responsibility for feeding may have shifted from family members to child care providers because these children spend the majority of their day in child care settings. METHODS: To examine the influence of feeding among low-income children in child care settings, feeding behaviors of child care providers in Head Start were observed and food consumption was assessed. Head Start, a comprehensive child development program that serves children from ages 3 to 5, was chosen because of the large percentage of minorities, the low-income status of the families, and the age of the children. Fifty child care providers (25 African-American; 25 Hispanic) randomly selected from Head Start centers in a large, urban southwestern city were observed on three mealtime occasions and self-reported feeding styles were assessed. Observed feeding behaviors were categorized into four feeding patterns based on their conceptual similarity to a general parenting typology (i.e., authoritarian, authoritative, indulgent, and uninvolved). Measures of food consumption were assessed on 549 children sitting with the child care providers during lunch at the Head Start centers. RESULTS: Indulgent feeding behaviors were positively related to children's consumption of vegetables, dairy, entrée, and starch; authoritative feeding behaviors were positively related to dairy consumption. CONCLUSION: This research highlights the important influence that child care providers have in the development of healthy and unhealthy eating behaviors in minority children. Implications for intervention training for child care providers to promote healthy eating among Head Start children are discussed.

RESUMO

PURPOSE: To examine relations among gender, self-generated smoking-outcome expectancies, and smoking in adolescents. METHODS: Students from one all-girls' (n=350; 53%) and one all-boys' (n=315; 47%) Catholic high school participated. Analyses included binary and ordinal logistic regression. RESULTS: For boys, smoking behavior was associated with buzz (odds radio [OR] = 1.92, 95% confidence interval [CI]: 1.31-2.83, p < .001), pleasure (OR = 1.47, 95% CI: 1.01-2.16, p = .044), taste/smell (OR = 2.17, 95% CI: 1.12-4.19, p = .022), stimulation (OR = 3.69, 95% CI: 1.32-10.28, p = .013), and exercise/sport impairment (OR = 2.84, 95% CI: 1.68-4.81, p < .001). Among girls, weight control (OR = 0.22, 95% CI: 0.13-0.36, p < .001), negative aesthetics (OR = 0.42, 95% CI: 0.28-0.64, p < .001), addiction (OR = 0.39, 95% CI: 0.28-0.55, p < .001), and negative mood (OR = 0.44, 95% CI 0.20-0.97, p = .041) predicted smoking. Buzz (beta = 2.88, p = .004) mediated the gender-smoking relationship. Moderators included negative social (beta = -0.45, p = .021) and enhance self-esteem (beta = -1.07, p = .024). CONCLUSION: Interventions might benefit from tailoring on gender differences in smoking-outcome expectancies.

RESUMO

BACKGROUND: More information about the physical activity of adolescents is needed. This study used objective measurement to investigate differences in activity patterns related to gender, body mass index (BMI), day, and time of day. METHODS: Eighth-grade adolescents (37 boys, 44 girls) wore the Manufacturing Technologies Inc. (MTI) accelerometer for 4 days and kept a previous-day physical activity recall diary in the fall of 2002. Minutes per hour in sedentary, light, and moderate/vigorous activity, as recorded by the MTI, and in nine activity categories, as recorded by the diary, were calculated for three time periods (6:00 am to 2:59 pm, 3:00 pm to 6:59 pm, 7:00 pm to midnight) on each day (Thursday through Sunday). RESULTS: Doubly multivariate analysis of variance revealed significant gender by day by time differences in sedentary (p =0.005) and moderate/vigorous (p <0.001) activity, but no significant BMI interactions. Except on Sunday, boys were less sedentary and more active than girls during the late afternoon period. Significant gender by category (p <0.001) and day by category (p <0.001) interactions were also found in the log data. Boys spent more time engaged in TV/electronics and sports, while girls spent more time in personal care. Three activity categories (sports, social interaction, active transportation) stayed at consistent levels across days, while others varied widely by day of the week. CONCLUSIONS: Except on Sunday, consistent gender differences were found in activity levels, especially for the late afternoon period. Significant increases in sitting, TV/electronic games, and chores were seen for weekend days. Results support strategies to reduce sitting and electronic recreation, which may increase physical activity.

RESUMO

PURPOSE: To evaluate the validity of the Previous Day Physical Activity Recall (PDPAR) as a physical activity diary in adolescents using two accelerometer intensity classifications. METHODS: One hundred eighth graders (47 boys, 53 girls) used the PDPAR as a daily diary and wore MTI accelerometers for four consecutive days. Measured time spent in moderate (> or = 3 METs) and vigorous (> or = 6 METs) activity was based on two published MTI cut-point limits (that of Freedson et al./Trost et al. and that of Puyau et al.). Spearman rank order correlations and Bland-Altman plots were used to examine agreement between MTI and PDPAR diary estimates of activity. RESULTS: MTI estimates of mean minutes per day of total moderate to vigorous physical activity (MVPA) were 65.2 (+/-43.2) using the Freedson et al./Trost et al. cutoffs and 17.5 (+/-18.5) using those of Puyau et al., while students self-reported 105.1 (+/-80.1) min.d(-1). Significant relationships were observed between the diary and MTI for total MVPA using either the Freedson et al./Trost et al. (r = 0.42) or Puyau et al. (r = 0.41) cutoff as well as raw counts (r = 0.44). Plots showed reasonable agreement between the diary and Freedson et al./Trost et al. MTI estimates of MVPA for daily totals of < or = 60 min, but the Puyau et al. estimates were consistently lower. Diaries overestimated activity as time increased when compared to either MTI cut point, especially on vigorous activity. CONCLUSIONS: Time estimates of MVPA differed by assessment tool, but diary estimates showed adequate association with the MTI. Diaries reflected intensity-specific activity, corresponding most closely with the Freedson et al./Trost et al. classification of moderate, but substantially overestimated vigorous activity regardless of cut-point method. This is likely due to the measurement characteristics of the PDPAR, which classifies activities in 30-min blocks, as well as the nature of common activities in which high levels of intensity are not sustained.

RESUMO

PURPOSE: Accelerometers are recognized as a valid and objective tool to assess free-living physical activity. Despite the widespread use of accelerometers, there is no standardized way to process and summarize data from them, which limits our ability to compare results across studies. This paper a) reviews decision rules researchers have used in the past, b) compares the impact of using different decision rules on a common data set, and c) identifies issues to consider for accelerometer data reduction. METHODS: The methods sections of studies published in 2003 and 2004 were reviewed to determine what decision rules previous researchers have used to identify wearing period, minimal wear requirement for a valid day, spurious data, number of days used to calculate the outcome variables, and extract bouts of moderate to vigorous physical activity (MVPA). For this study, four data reduction algorithms that employ different decision rules were used to analyze the same data set. RESULTS: The review showed that among studies that reported their decision rules, much variability was observed. Overall, the analyses suggested that using different algorithms impacted several important outcome variables. The most stringent algorithm yielded significantly lower wearing time, the lowest activity counts per minute and counts per day, and fewer minutes of MVPA per day. An exploratory sensitivity analysis revealed that the most stringent inclusion criterion had an impact on sample size and wearing time, which in turn affected many outcome variables. CONCLUSIONS: These findings suggest that the decision rules employed to process accelerometer data have a significant impact on important outcome variables. Until guidelines are developed, it will remain difficult to compare findings across studies.

RESUMO

PURPOSE: This study investigated differences between two ethnic minority groups on five hypothesized correlates of physical activity (beliefs about the value of physical activity, normative modeling, perceived barriers, outcome expectations, and self-efficacy). DESIGN: A cross-sectional sample consisting of 246 African American and Hispanic women 40 to 70 years of age was used. Multivariate analysis of covariance including interactions with education and income was used. RESULTS: A three-way interaction (ethnicity by education by income) was significant for perceived barriers. In addition, a two-way interaction (education by income) was significant for normative modeling. CONCLUSIONS: Ethnic differences by education and income were associated with some correlates of physical activity; therefore, it is important to consider this diversity when designing physical-activity interventions for minority women.

RESUMO

The expected outcomes of drug use figure prominently in models of drug motivation. This report presents the relations between self-generated expected outcomes of smoking and smoking behavior in 674 adolescents. Expected outcomes of smoking were related to current smoking, experimentation, and susceptibility among never-smokers, even after controlling for key correlates of smoking behavior, including gender, grade, ethnicity, and peer smoking. Although more negative than positive smoking outcomes were accessible from memory, more positive than negative expected outcomes were correlated with smoking behavior. Both the content and number of self-generated expected outcomes provided unique associative information. In sum, greater elaboration of smoking-related memory networks, as well as the specific content of those networks, appear to be associated with smoking behavior.

RESUMO

BACKGROUND: Understanding the factors that contribute to physical activity (PA) in Mexican-origin adolescents is essential to the design of effective efforts to enhance PA participation in this population. METHODS: Multivariable logistic regression was used to identify sociodemographic and behavioral correlates of self-reported PA in school and community settings in 1154 Mexican-origin adolescents aged 12-17 years in Houston, TX. RESULTS: The majority of adolescents were born in the US (74%), approximately half (51%) were overweight or obese, and nearly three-quarters (73%) watched more than 2 hours of weekday television. Similarities and differences by setting and gender were observed in the relationships between sociodemographic and behavioral characteristics and PA. In boys, parental education and attending physical education (PE) were positively associated with PA across multiple PA outcomes. Adolescent linguistic acculturation was inversely associated with participation in community sports, whereas parental linguistic acculturation was positively associated with PA at school. In girls, PA in school and community settings was inversely associated with TV viewing and positively associated with PE participation. CONCLUSIONS: These findings highlight similarities and differences in correlates of PA among boys and girls, and point toward potential sources of opportunities as well as disparities for PA behaviors in Mexican-origin adolescents.

RESUMO

BACKGROUND: Identity theorists maintain that domain-specific self-concepts help explain the differential investment of people's time and effort in various activities. PURPOSE: This study examined the contribution of athletic identity and three key demographic variables to physical activity and sports team participation. METHODS: Students in Grades 4-5 (n=391, mean age 9.9 years, range 8-13 years, collected in 2003) and Grades 7-8 (n=948, mean age 13.6 years, range 11-15 years, collected in 2002 and 2006) completed the 40-item Athletic Identity Questionnaire, which measures self-perceptions of athletic appearance; competence; importance of physical activity and sports; and encouragement for activity from parents, teachers, and friends. Hierarchic multiple regression analyses in 2008 assessed the effects of athletic identity, race/ethnicity group, gender, and overweight status on 7-day moderate-to-vigorous physical activity (MVPA) and organized sport team participation in each age group. RESULTS: In children and adolescents, the global score of athletic identity was independently, positively related to MVPA (p<0.0001, p<0.0001, respectively) and team participation (p<0.0001, p<0.0001, respectively), after controlling for demographic variables. More variance in MVPA was explained in children (23%) than in adolescents (5%), in contrast to team sports (5% in children, 15% in adolescents). In the subscale analyses, positive relationships for appearance, competence, importance, and parental encouragement persisted independent of demographic factors. CONCLUSIONS: Results support the role of athletic self-concept in promoting physical activity and organized sport participation in children and adolescents.

RESUMO

BACKGROUND: This article describes the adaptation of the Athletic Identity Questionnaire (AIQ) for Adolescents for use with children and evaluates its construct validity. Based on a theoretical model supported in adults and adolescents, the AIQ-Child measures the general attribute of athletic, which encompasses exercise, sport, and physical activity and assesses 4 dimensions: appearance, competence, importance of activity, and encouragement from 3 sources (parents, friends, teachers/ other adults). METHODS: The hypothesized 4-factor model was tested using structural equation modeling in 2 samples of 9- and 10-year-old children that were ethnically diverse (N = 432) and Hispanic (N = 504). RESULTS: Confirmatory factor analysis using LISREL 8.71 supported the 4-factor structure in a 40- or 38-item version in sample 1 (RMSEA = .039, .041) and sample 2 (RMSEA = .038, .038). As in the adult and adolescent models, there was also support for a higher-order model. The AIQ-Child factors were positively related to physical activity (r = .51 to .68) and fitness (r = .15 to .41) and negatively related to TV/computer use (r = -.28 to -.03) and adiposity (r = -.32 to .04). CONCLUSIONS: Findings support the factorial and construct validity of the AIQ-Child and its use as a self-report instrument in younger children.

RESUMO

Current feeding measures have been developed based on the premise that a child's obesity risk is increased when parents exert high levels of control over feeding. Although these measures provide useful ways to assess parental restrictiveness in feeding, they do not capture other important aspects of feeding that describe the behavior of parents not overly concerned about child obesity. Alternative measures are important to develop, especially for minority populations where concerns about child obesity are often not a significant determinant of parental feeding practices. The current study describes a culturally informed method used to develop a broader assessment of parental feeding strategies across two low-income ethnic groups. To be able to accurately measure cultural differences associated with feeding, qualitative and quantitative methods were used to assure conceptual, linguistic, and measurement equivalency across African-American and Hispanic parents. Based on responses from 231 parents, mean differences in feeding strategies were found with Hispanic parents reporting significantly more parent-centered/high control and child-centered feeding strategies compared to African-Americans. Furthermore, the relationship between children's weight status and parental feeding strategies varied by the two ethnic groups and child gender. Implications of these results for understanding the role of parental socialization in the development of child obesity are discussed.

RESUMO

BACKGROUND: Psychometrically sound measures are considered a necessary condition for valid research. This study used structural equation modeling to examine the cross-cultural equivalence of a widely used measure of parental beliefs and practices regarding child feeding, the Child Feeding Questionnaire [Birch L.L., Fisher J.O., Grimm-Thomas K., Markey C.N., Sawyer R., Johnson S.L. Confirmatory factor analysis of the child feeding questionnaire: a measure of parental attitudes, beliefs and practices about child feeding and obesity proneness. Appetite 2001;36:201-10]. METHODS: Low-income parents of 101 Black and 130 Hispanic pre-school children (126 girls, 105 boys) completed a reduced version of the CFQ. RESULTS: Confirmatory factor analyses using LISREL 8.51 supported the hypothesized factor structure but revealed cross-cultural conceptual problems on the perceived child weight factor and problematic items on the restriction factor that were addressed in a modified model. Invariance analyses demonstrated invariance of factor structure, loadings, and covariances in the modified model across ethnic groups. MANCOVA, that controlled for parent BMI and marital status, revealed ethnic differences on the child feeding responsibility, child weight concern, and perceived weight of child factors that were moderated by parent education and child BMI. CONCLUSIONS: Results supported the use of a modified version of the CFQ among Blacks and Hispanics and revealed no ethnic differences on factor scores, except on interactions with parent education and overweight status of child.
